She told them he had a pistol, and how during a fight in early December, he pulled her hair, slammed her head into a wall and tried to shove a sock in her mouth, according to a domestic violence report.

She told them he threatened to "personally kill" her if she ever tried to take their kids away.

How one day when she left work, or was walking down the street, he would hurt her.

"You won't even know it," he told her, according to court documents.

Authorities say that tragic scenario played out late Sunday night during an hours-long incident that started with Brown fatally stabbing his estranged wife at a restaurant in Seminole County.

It ended when deputies found Henry Brown, 30, and the couple's two young children dead in a pickup truck on the side of Interstate 4 west, according to the Seminole County Sheriff's Office.

Deputies said it appears Brown shot and killed the children — a 1-year-old girl and 4-year-old boy. He then shot and killed himself, according to the Sheriff's Office.
